Martin Demichelis has said the way Barcelona play football is without equal after Manchester City were beaten in the Champions League.
Demichelis started for City but was dismissed in the second half after fouling Lionel Messi when the forward was through on goal.
A penalty was awarded and then scored by Messi, with Barcelona going on to win the game 2-0 when Dani Alves added a second.
There was some protest regarding the penalty decision from the City camp but Demichelis told an Argentinean radio station that he has no complaint.
“I feel sad about it. It’s impossible to make an objective analysis of the play. I can’t blame the referee,” the former Malaga player said.
“On a personal level I am very sad. I feel nervous and powerless.
“There were two games: One before the penalty and one after,” Demichelis continued.
“These mistakes make you and hurt you, but the penalty killed the game of football.”
Demichelis was however impressed by Barcelona, but refuses to give the tie up for lost.
“I don’t think there is any team that can match the way Barca play,” he added.
“The hardest thing to do is get the ball from them.
“But we have to go to the game in Barca with faith.”
Demichelis was also asked his thoughts on the form of Lionel Messi after some critics claimed he was no longer interested in football.
“Messi’s injuries are in the past now. I know he lives for football,” Demichelis replied.
